Letters Patent No, 101,7 3], dated April 1.2, 1870.

.IMPROVEMENT IN PoTATo-szzpARAroRlsA The Schedule referred to in these Letters Patent and making part o! the same.

To all whom tmayconce'rn Be it known thatfl, RICHARD HAVLAND, ot' North Branch, in the county of Baltimore and State of Mary-V land, have invented a new and useful Improvement in Potato-separators; and I do hereby declare that the following'is a full and exact description thereof, reference heilig had to the accompanying drawings and to the letters of reference marked thereon.

In the accompanying drawings-f.l Figure 1 is a perspective view of my machine, the top of the box being removed to show the cylindrical screen, which is made of \vo\en'wire.- l

Figure 2 is a vertical section of my machine. Figure 3 is a' detached view of the spout, for discharging the largest potatoes. i

Figure 4 represents the flat stripsoi' iron or other material, which may be employed as a substitute for wire-ganze, for makingthe screens. Figure 5 represents a plate of perforated metal, which also may be employed as a substitute for wire or strips.

Theframe A and box B may bev of" any suitable form. i

Upon an inclined shaft, C, are' placed tw'o cylin-` drical screens, D and E, made ot' woven wire,tiat strips, or perforated sheet metal., 'lhe meshes in the inner cylinder D are larger than those in the cylinder .These screens are inclined, so that potatoes fed into the machine at spout G will slowly pass from right to left, when the screens are set in rotation by means ot' crank F, or by any other suitable means.

By this machine the potatoes are separted into three sizes, according to the usual practice of' farmers.

The smallest potatoes drop through the meshes ol` both of the screens D and E, and then roll toward the right hand upon the tiat inclined screen H, in the 'lower part of the box B. The screen H separates the dirt from the smallest potatoes.

The medium-sized potatoes fall through the inner cylinder D, and are'delivered by the spout I, fig. 2, at the side oi' the machine; and the largest potatoes pass along the'inner screen-D, andare delivered by the spout K, figs. 2 and 3.

1t may be better, in full-sized inaehines, to let the Witnesses:
